Blender 2.73a crashes on start up
If the problem is related to having a PYTHONPATH environment variable set, you can do the following so you don't have to modify your PYTHONPATH variable. I am running 2.75a and this fixed my problem.


Make a batch file somewhere like your desktop


To do so, create a blank .txt document and name it blender.bat (MAKE SURE THE EXTENSION IS .bat and not .txt)

Edit blender.bat and add the text below

set PYTHONPATH=""
cd C:\Program Files\Blender Foundation\Blender\
start blender.exe

Your blender path may be different, so make sure you find the correct path
run blender.bat


This will temporarily set the PYTHONPATH to "" (nothing) during your blender session but is restored after you close.
